[PATCH 4/4 for opensm] opensm.spec.in: Improve portability

[Bart Van Assche]

Add support for Debian and for other systems that do not support
chkconfig. See also http://refspecs.linuxbase.org/LSB_4.0.0/LSB-Core-generic/LSB-Core-generic/command.html.

Also, after having installed /etc/init.d/opensmd on a system where
systemd is present, tell systemd to reload the files in /etc/init.d.
